Cryptoexplosive breccia discovered in large Nanling granitic batholith

Cryptoexplosive breccia was discovered by the author in large Nanling granitic batholith for the first time in 1987, which is described in the paper. This kind of rock controls the formation of rich uranium ore, and has no apparent relation with volcanic activities in the exposed area. In terms of petrology, mineralogy and geochemistry, cryptoexplosive breccia is obviously distinct from the 'bulk' granite, and is not a supplemental body to 'bulk' granite but an exotic product. Its formation is related with crust-derived materials and also having mantle-derived materials involved
